DEFENDER SERIES 300105-53-01 Full Size Saddle Box 71 x 19.7 x 17.7 Black is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Very disappointing I was looking for a mid-range box that wasn't too light and junky but wasn't real expensive either. I was very excited to see that Weather Guard seemed to be offering just what I was looking for with your Defender Series. Unfortunately, there is no defense for the lack of quality in this tool box.The first one arrived with a big dent in the bottom corner and the top dented from one end to the other, with the keys locked inside (it appeared I wasn't the first to return it). Amazon sent me another one and gave me 30 days to return the first one. Second one dented less, but still not acceptable. Amazon to the rescue and I got my third box, which only had one dent in the top that looked like somebody had hit it sharply with a ball peen hammer. Better than box 1 and 2 and maybe I could live with it, although it was still a lot of money and already dented. I am not easy on things, but the one I am retiring from a smaller truck didn't have any dents as bad as that one. As I looked it over deciding whether to keep it or not, I noticed a few other things. When I placed the box in my truck, I noticed that the sides of the box were not parallel. If I lined up one side, the other ran off at an angle. Then I noticed that the rods between the latches had no cover over them and would definitely be getting pushed against by contents in the box, making it hard or impossible to open. Even the cheapest boxes cover these. Then I realized that the reason the tops were always dented was because the aluminum was so flimsy. I know I was slow to catch on to this, but I was blinded by the Weather Guard name that I thought meant something. When they arrived dented, I initially blamed the lack of protection in the shipping box, but then I realized that if you have to cushion it and mark it "fragile" in order to ship it, well it's not a very rugged tool box, is it? It is not a box you could stand on, or even set something down hard, without denting it. One of the big selling points for the box for me was the fact that you could push the button and the lid opened, enabling you to open it with your hands full. But because the box was so poorly made, the cover hung up on the box about half the time, requiring a push to get it to open.You also can't latch both sides securely by pushing down on just one side of the cover, requiring a trip around the truck to push down the other side. The bolts on the shocks were about to fall out, the flimsy aluminum partitions were bent...I sent it back for a refund. I can not recommend the Defender Series to anyone. It is very disappointing that Weather Guard - a name synonymous with quality - would sell something that isn't even as good as most of the less expensive boxes I have looked at.

This is mounted into place using hooks that will attach under the bed rail of your truck. There is no drilling necessary for this installation.

Water/Snow inside

Has anyone had snow and water blow up thru the sides of this box? Where the box mounts to the truck bed rail there are the cut outs for the bolts to slide back and forth. Has anyone had issue with this? If so what can you do to stop this from happening? I had it happen when taking the truck thru the car wash and then the other day when snow was blowing around in the bed it blew up inside thru those openings.
